GYTR 2014 YZ250F COMPLETE EXHAUST
PRODUCT: GYTR by FMF’s titanium RCT Factory 4.1
complete exhaust system for the 2014 Yamaha YZ250F
with spark-arrestor capabilities.
POSITIVE: Saves over a pound of weight from the
stock unit in the 250F world—this is huge. Unlike most
aftermarket exhausts, GYTR’s system allows the use of
stock Yamaha heat shields. The addition of spark-arrestor
capabilities makes it legal for off-road use and meets AMA/
FIM sound requirements. The GYTR system increases
midrange power and pull while improving top-end over-rev.
NEGATIVE: For riders who like lots of bottom-end power
that the 2014 YZ250F produces, the GYTR pipe takes
away some of the bottom-end torque. We noticed minor
amounts of popping after installing the system, so minor
ECU mapping is required.
BOTTOM LINE: GYTR’s complete exhaust system
by FMF for the all-new 2014 Yamaha YZ250F improves
midrange and top-end power, turning it into a revving
machine, and with the addition of spark-arrestor capabilities, making it legal for off-road use is always a plus.
PRODUCT: Energy Suspension’s OEM replacement
chainguide, slider and roller kits for newer Kawasaki
KX250F and KX450F motocross bikes are designed to
extend wear life.
POSITIVE: Because the OEM sliders are like yogurt, the
Energy Suspension sliders are just getting broke in when
the stock units are ready to be thrown away. There is no
KX250F/450F CHAIN SLIDER KIT
loud chain-slapping noise associated with other
aftermarket slider kits. The black, gray or red color options
look cool once installed. The guide, bearings, rollers and
slider all come in the kit for just under $100.
NEGATIVE: Installing the swingarm slider piece of the
kit took a little elbow grease to line up the mounting holes.
This piece is easier installed when it has been sitting in the
sun or warmed up slightly with a heat gun.
BOTTOM LINE: We tested the Energy Suspension chain
slider kit on our project bike at the 10-Hour endurance
race. Energy designed these kits primarily for motocross
use and OEM replacement items, but they held up great
to 10 hours of constant pounding from our pro-level team
and came out of it with life to spare. If you are looking
to replace stock Kawasaki sliders and rollers and adding
some wear life, Energy Suspension’s kit is a great option.
